. CONTAINER.

Application filed March 7, 1916, Serial No. 82,521.

' citizen of the United States, residing at Buffalo, in the county of Erie and State of-New York, have invented certain new and useful Improvements in Containers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to containers, and with respect to its more specific features to containers for liquids, such as milk bottles.

One of the objects of the invention is the provision of an inexpensive and efficient liquid container made of fibrous material and strong enough to withstand the strains that it has to undergo when in use.

Another object of the invention is the provision of a practical container of the character referred to having a shoulder to cooperate with a closure, such as a fiat sealing-cap commonly used for closing milk bottles.

Another object of the invention is the provision of a ligh container, of a sanitary character, and of such inexpensive nature that 1t may be thrown away or destroyed after a sin le use.

6ther objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which Wlll be exemplified in the construction herein ness adapting it to retain its shape when in container form, such as a cylindrical or con1- cal form. Its best adaptation will probably manifest itself in the c nical form, and the invention is herein dis losed in connection with such forms.

The numeral 1 indicates the bod of the Specification of Letters Patent.

container, formed of a tough manila sheet of paper folded into a generally conical shape, the lower edges of the cone being turned upwardly, as at 2, to receive the downwardly projecting flange 3 of a bottom 4.

The upper or neck portion of the body 1 is outwardly reversely folded on itself, as at 5, the reverse fold being brought against the outer wall of the body 1 and forming a lateral shoulder at the mouth of the containers Adjacent the mouth of the container and slightly below the same is disposed a stiffening cap-supporting member, or ring 6. This ring may be of any suitable material adapted to subserve the purposes of the ring, but preferably is a metallic ring circular in cross section and of a cross sectional diameter of a substantial size and referably thicker n the embodiment illustrated in Fig. 1, the ring 6 lies substantially tangentially and "circumferentially against the inside wall of the container, and is covered so that the contents of the container does not come in contact therewith. Preferably the cover for the ring comprises a flexible strip of manila paper, which lies on the ring and closely conforms to the periphery thereof at the upper, lower, and inwardly presented faces of the ring, as indicated at 7 8, and 9, and is attached or secured to the body 1 above and below the ring so as to cooperate with the body to enclose the ring. Suitable adhesive may be employed to attach the cover strip to the body, and this adhesive may be paraffine, into which the strip may erally extending shoulder, referred to. The

cover strip extends completely around the inner wall of the tontainer body and the ring 6, being lapped, as indicated by the line 10.

In the embodiment indicated in Fig. 2, the ring 6 lies against the outside of the wall 1 of the container body, bein supported in a groove 11, span in the wal such spinning providing a bead or, shoulder. 12 of an inner wall of the container opposite the groove 11 and the ring 6. In order to securely keep the ring 6 in the groove in which it is seated, a strip of flexible material similar to that above referred to, is applied to the outside wall of the container, being attached to the container above and below the ring, and having a portion conforming to the outer face of the ring. The strip in this form may also be applied to the container before the shoulder 5 is formed, so that the reverse folding of the upper edge of the container and the applied strip will result in a folded portion of the strip lying between the plies 5 and 6 of the folded portion of the body 1.

In the form illustrated in Fig. 1, the ring 6 provides a shoulder on the inner wall of the receptacle for the support of a sealing cap which may be a fiat disk, such as commonly used as a closure for milk bottles, and illustrated in Fig. 1. In the form illustrated in Fig. 2, the ring 6 also forms a supporting shoulder for a similar closure, the closure, however, seating itself directly upon the head 12 of the body material instead of upon the cover material of the other form. In both forms the ring 6 being of substantial cross-section provides a stiff member which retains its circular form and maintains the neck of the container, adjacent the mouth, in predetermined shape, thereby efliciently resisting strains tending to crush the container transversely. The folding of the mouth end of the container so as to provide the shoulder 5 stifi'ens the edge of the container, andalso provides the laterally tending shoulder 5 which offers convenient means for grasping and lifting the container.

The container is made liquid tight by coating the same with parafline or other similar material, both inside and outside, and this coating is preferably effected after the container has been otherwise completed, but may be effected by coating separate parts thereof during the course of manufacture, if preferred. By making the cross section of the ring thicker than the body material, it may be seated in the groove 11 of the embodiment in Fig. 2, with its inner face projecting at one side of the face of the body material, and its outer face projecting at the opposite side. In this-wise, the ring will be supported mainly within the thickness of the body material, and be more securely held from upward or downward movement.

The neck of the receptacle, adjacent the mouth and above the cap receiving shoulder converges upwardly toward the mouth, and the cap is forced past the slightly overhanging extreme upper port-ion, and is held securely seated on the shoulder, and prevented from upward movement by said overhanging portion. In the conical form illustrated, the walls naturally converge to provide the overhanging portion referred to. In a cylindrical receptacle the neck may be shaped to provide such overhanging portion adjacent its mouth.

Thus by the above-described construction are accomplished, among others, all of the objects hereinbefore referred to.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and'not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described,

and all statements of the scope ofthe invention, which as a matter of language the ring and conforming to the peripheral face of said ring at the upper, lower, and inwardly presented faces of said ring.

2. A container comprisin in combination, a paper body, and a sti ening cap-supporting ring on the inside of the container adjacent its month, said ring being thicker than the body material, and a cover for said ring, comprising a separate-flexible strip attached to the container above and below said ring, and extending over the edge of the mouth to the outside of the container.

3. A container comprising, in combination, a paper body, a stiffening cap-supporting ring on the container adjacent its mouth, a flexible strip over said ring and secured to the container above and below said ring, the body material and said flexible strip being outwardly reversely folded into position against the outer wall of the container to form a lateral shoulder at the mouth of the container.

4. A container comprising, in combination, a conical paper neck reversely folded at its mouth to form a shoulder, a stiffening ring on the inside of the container below its mouth, a flexible strip covering said ring, attached to the wall of the container above and below said ring,'and folded over the edge of the neck so as to conform to said shoulder, a portion of said strip conforming closely to the upper, lower, and inner faces of'said ring.

"5. A container comprisin in combination, a fibrous non-metallic Eody, a stifi'ening cap supporting member lying ci1'cun1 ferentially and substantially tangentially 5 against the wall of said body adjacent its mouth and ,a coverco-operating with the wall of said body to enclose said stiffening member.

6. A container comprising, in combination, a fibrous non-metallic body, a stiffening cap supporting member lying circumferentially against the wall of said body adjacent its mouth, and a cover strip, separate from said body but attached thereto, co-operating with the wall of said body to enclose said stiffening member.
